11： 如何设置动态域名(可选)
#首先去 [url]http://www.3322.org[/url] 申请一个动态域名
#然後修改 /etc/ppp/ip-up 增加拨号时更新域名指令
sudo gedit /etc/ppp/ip-up
#在最後增加如下行
w3m -no-cookie -dump 'http://username:password@members.3322.org/dyndns/update?system=dyndns&hostname=yourdns.3322.org'

将username:password按格式替换为你的用户名和密码 hostname替换为你的域名，其他不必更改。以上设置将在拨号时自动将动态域名解析挂载好。
